INTERNAL-COMBUSTION ENGINE.

rality of radial cylinders towhich the explosive mixture is led by wayof an induction case. My improvements relate specifically to thedetailed construction of this induction case, whereby a more evenmixture is distributed to all of the cylinders.

In the accompanying drawings, Figure I, is a sectional view of a part ofthe engine embodying my invention, and

Fig. II,-is a side elevation of the induction case.

The cylinders 1, of the engine receive their explosive mixture by way ofradial induction tubes 2, all of which lead from a cen trallysituatedannular induction case 3 which surrounds the shaft 4, of the engine in aplane corresponding to that in which the tubes 2, lie. Theinduction casecomprises an-outer wall 5, and an inner wall 6, with a rotarycentrifugal fan 7 mounted between the two. The inlet opening 10, bywhich an explosive mixture from the carbureter is drawn into theinduction case is formed in the side 5, of the induction case toward itslower edge. For this purpose the side 5, is ofiset as shown, so as to beremoved from the plane in which the disks of the fan rotate.

In order that the inlet 10, may discharge as near as possible to thecenter of the induc-' tion case, the inner-side of this opening isprotected interiorly by the baflie plate 11, the outline of whichappears in dotted lines in Fig. H. The shape of this bafile plate issuch-that the incoming stream of explosive mixture is deflected acrossits surface and around its inner ed e toward the center of the fan, bywhich sai mixture is immediately taken up and further atomized anddriven by its centrifugal action into the tubes 2. These tubes projectslightly within the periphery Specification ofLetters Patent.

of the induction case, as shown at 15, so as to prevent any liquid fueldrawn in with the explosive mixture from accumulating in the lower partof the induction case and being thence driven in liquid form into thelowermost pipes.

To properly dispose of such a'ccumulatf.

ing liquid the baflle plate 11, is so constructed as to provide aby-pass in the form of a slot 12, along its edge and in proximity to theedge of the inlet 10, whereby accumulating fluid flowing into contactwith the stream of the incoming mixture is'takenup and delivered nearthe center of the fan, and again atomized and driven by centrifugalforce into the tubes 2.

In this way a rich mixture is evenly disannular. induction casecentrally mounted near the plane of these cylinders; induction tubesconnecting the periphery of the in.- duction case with the cylinders; acentriiugal fan rotating in said fan casing; an inlet opening for theinduction case oflset from the plane in which said tubes enter it,delivering an explosive mixture in the central region of the fan casing,and a bafiie" plate interposed within the induction case to deflect theincoming mixture toward the center of the same, with a by-pass at thelower edge of the said bame plate, whereby fluid driven by the fan fromthe mixture toward the periphery of the fancasing is'allowed-to escape,and again come into contact with the incoming mixture.

In testimony whereof, I have hereunto signed my name, at Philadelphia,Pennsylvania, this ninth day ofSeptembe'r, 1916.
